ProxyTunnel is a browser-based web proxy service designed to help users access websites, browse anonymously, and hide their IP address. It functions as an intermediary layer between the user’s device and the internet, routing requests through a proxy server to prevent direct IP exposure to target websites. The service operates without requiring any software installation, downloads, or account registration. It is intended for use on restricted networks such as schools, workplaces, or public Wi-Fi, as well as for users who want a quick and simple way to improve their online privacy while browsing publicly available websites. The tool offers several core capabilities. It provides basic IP masking to reduce direct identification of the user’s real IP address. It uses a web access layer that allows users to bypass regional restrictions, school or work blocks, and certain content filters, including some Cloudflare barriers. When available, the connection between the user and the proxy endpoint is encrypted using HTTPS/TLS. The service supports both HTTP and HTTPS web protocols and works across desktop and mobile browsers, making it compatible with Windows, macOS, Linux, Android, iOS, and routers without any additional setup. It is powered by a reverse proxy architecture intended to maintain reasonable speed for video streaming and heavy website browsing. Typical use cases include accessing blocked websites from educational or workplace environments, masking one’s IP address when using public Wi-Fi, and browsing with a basic level of privacy awareness. The workflow is straightforward: users navigate to the ProxyTunnel website, enter a URL, and the proxy server fetches and displays the requested content within the browser. No configuration or technical knowledge is required. The service is free, though it includes a voluntary donation option to help maintain server costs, with a specific warning that donations must be sent only via the TRC20 network to avoid permanent loss of funds.
